James Canton spent two years sitting beneath an 800-year-old oak tree near his home in Essex, watching acorns fatten and butterflies land on the massive knurled grey trunk. Sometimes he sat in the branches too.

Canton, a lecturer at the University of Essex, recalls how it helped him feel a “sense of connection”. “We’re happier sat in an oak tree ten foot from the ground, watching blue tits feeding on caterpillars – involved and immersed in that natural world.” He went on to write a book called The Oak Papers about that time spent studying the Honywood Oak.

For years, it was easy to forget that we used to be a woodland nation: around 6,000 years ago untouched swathes of oak, hazel, birch and pine blanketed an estimated 75% of the UK. But in recent months the felling of the Sycamore Gap tree next to Hadrian’s Wall in Northumberland has put our relationship with trees, and the natural world more widely, back under the spotlight.

Two men are due to be sentenced today for the crime that has been called a “mindless destruction”. Canton calls it a “symbolic” moment. The felling of the Sycamore Gap has prompted calls for stricter legal protections for trees, not only to help prevent similar crimes in future but also to help the public appreciate the value of trees at a time when many of our woodlands are in poor health and targets for tree-planting are not being met.
